Trailer Coupler Lock for 1-7/8, 2 and Most 2-5/16-Inch Tongues – Master Lock 379ATPY Black

Trailer coupler lock blocks a parked trailer tongue from being connected to an unauthorized tow vehicle. Master Lock 379ATPY uses a visible keyed body sized for 1 7/8-inch, 2-inch and most 2 5/16-inch couplers on compatible utility, boat, RV and camper trailers.

The polished black zinc construction is designed to resist weather, rust and corrosion, while the locking mechanism is engineered to resist picking and prying. One lock and two keys are included, allowing a spare to be stored separately. Position the lock on a clean, fully closed coupler and confirm that the body seats without interference before turning the key. This device helps deter theft but should be combined with sensible trailer storage and key control. The listing includes single- and six-lock packages, so choose the required quantity and keep each corresponding key set identified.
